Some popular US dictionaries list only the spelling angstrom. [2] [3] The unit's symbol is Å, which is a letter of the Swedish alphabet, regardless of how the unit is spelled. [1] [4] [3] However, "A" [citation needed] or "A.U." [11] [7] may be used in less formal contexts or typographically limited media.
The Ångström unit (1 Å = 10 −10 m) in which the wavelengths of light and interatomic spacings in condensed matter are sometimes measured is named after him. [6] The unit is also used in crystallography as well as spectroscopy. The crater Ångström on the Moon is named in his honour.
Conversions between units in the metric system are defined by their prefixes (for example, 1 kilogram = 1000 grams, 1 milligram = 0.001 grams) and are thus not listed in this article. Exceptions are made if the unit is commonly known by another name (for example, 1 micron = 10 −6 metre).
The myriameter [147] (sometimes also spelled myriometer; 10,000 meters) is a deprecated unit name; the decimal metric prefix myria-[98] (sometimes also written as myrio-[148] [149] [150]) is obsolete [99] [100] [101] and was not included among the prefixes when the International System of Units was introduced in 1960.
Quantities, Units and Symbols in Physical Chemistry, also known as the Green Book, is a compilation of terms and symbols widely used in the field of physical chemistry. It also includes a table of physical constants , tables listing the properties of elementary particles , chemical elements , and nuclides , and information about conversion ...
Conversion of units is the conversion of the unit of measurement in which a quantity is expressed, typically through a multiplicative conversion factor that changes the unit without changing the quantity. This is also often loosely taken to include replacement of a quantity with a corresponding quantity that describes the same physical property.
The fermi is a unit of distance used in nuclear physics equal to 1 fm. [9] The angstrom (symbol Å) is a unit of distance used in chemistry and atomic physics equal to 100 pm. The micron (μ) is a unit of distance equal to one micrometre (1 μm). The basic module (M) is a unit of distance equal to one hundred millimetres (100 mm).
The angstrom is a unit of length equal to 0.1 nanometre, also spelled ångström (lower case). Ångström or Angstrom may also refer to: People.
